Now more than ever.

This is the second article from my series on migrating to the cloud, it is focused on best practices in cloud migration, its advantages, and disadvantages.

In recent years, the world we have known has undergone substantial change. We are constantly challenged to alter our behaviour, as well as the way we operate and carry out our regular tasks. At both work and at home. Most people nowadays work remotely due to the circumstances in which we must live. It is a fantastic source of comfort in this wild time, and the home office has evolved into a full-fledged workplace. This has not been an easy shift for everyone. Companies that have begun the digital transformation should find it much easier to adjust to changing conditions than those that have not.

It is tempting to imagine that technology helped businessess stay open through the whole outbreak of coronavirus. There is a consistent technology that is cloud computing, when it comes to enabling employees to work from home while retaining business-critical services.

Cloud computing has enabled organisations to continue operating normally in the face of a crisis that might have easily brought corporate operations and output to a halt.

Staff can now work from home thanks to cloud technologies.

The advantages of cloud computing may differ depending on the type of organisation. For many businesses, for example, it will simply be a matter of allowing employees to work from home.

With staff being forced to work from home, AWS Cloud has given them the flexibility to safely access the network using their home internet and their own device. None of this would have been feasible without the cloud.

DaaS (Desktop as a Service) services have been built for this purpose. With such solutions, an employee may utilise corporate resources anywhere in the globe from any device. In addition, the whole process is incredibly safe because no information is saved locally on the computer of the employee, An example of this type of service is Amazon WorkSpaces.

If a corporation had AWS Cloud in place before to the pandemic and needed to scale up the number of users and servers in the cloud due to the high number of employees working from home. The ability to rapidly scale up and down as needed in a short period of time is a significant feature of cloud computing.

Typical Data Center

Large enterprises and businesses frequently employ their own data centres. It offers them a sense of security and provides them the impression that they have complete control over IT concerns. However, for the Data Center to function well, both hardware and people to administer it are required. Their absence (due to, for example, an illness like Covid-19) may result in delayed incident response and, in severe instances, server failure. Furthermore, in cases where leaving the house is not an option, it is worthwhile to seek a solution that will allow us to accomplish our obligations remotely.

The functioning of data centres may be jeopardised not just by personnel issues related to the present global scenario. Accidents, infrastructure problems on our DC's side, and, in extreme situations, natural disasters can all create pauses in service delivery for which we have no control over the length.

Is there any way to solve this problem?

Is there a solution that will solve our digital business's problems? No, not at all. There is no such thing as an ideal answer. However, there is something that can make our lives a lot easier. I'm talking about the cloud.

A well planned cloud infrastructure, together with a well executed security strategy and created disaster recovery solutions, can undoubtedly shield us from the repercussions of many unanticipated catastrophes. How? I'll explain in more detail in the next paragraphs.

I previously identified potential issues with the data centre. Let's face it, servers are the foundations upon which our digital businesses are built. They offer the environment in which our apps may execute. If the servers fail, even the best software will stop operating, and your firm will lose money. We may avoid this by transferring them to the cloud.

Infrastructure as a Service

How are we going to do this? Consider the notion of Infrastructure as a Service (IaaS). Let us use virtual machines to replace actual equipment. Cloud vendor server rooms (public cloud providers) are big, powerful complexes. They have tens of thousands of servers, its own internal network, and several power sources.

You may believe the instance is operating on a certain physical server, and it might also crash. Yes, it is possible. However, significant cloud providers such as AWS, Microsoft Azure, or Google Cloud Platform, are constructed in such a manner that if one of the hypervisors (tools for controlling virtualisation processes) fails, your instance may be started on another and continue to run.

In addition, the entire server room of a particular provider might hypothetically fail, but because of the high availability solutions and the flexibility of cloud computing. You can still operate even if you presume to have even the worse scenario and a massive disaster which disables one of these regions.

Using traditional methods, you would rent servers in another data centre, instruct your admins to instal systems and setup environments, and then begin the time-consuming process of recovering data from backups. Of course, as long as there are backups...

Storage and Security

You also don't have to be concerned about the data. Object storage, such as AWS S3, ensures data durability of 99.999999999 percent, implying that data cannot disappear. Furthermore, you may store the same data in other locations throughout the world, such as Europe and Asia, which eliminates the chance of losing them (for example, as a result of a major disaster). As a result, even if the worst-case scenario occurs, you will be able to return to work and conduct business as normal within a few hours at no additional expense. This is a significant advantage of cloud computing over traditional on-premises systems. No traditional solutions will be able to deliver the same level of flexibility and dependability.

Platform service - a solution for difficult times.

It is critical to safeguard oneself in as many ways as possible during a crisis. If you've previously employed the services of a small business that has normally performed admirably, you can't be sure how the worldwide crisis will alter the quality of its services. Is the SLA going to be met? Will any performance concerns identified by your clients be addressed promptly? Unfortunately, none of us know for certain. These expectations are met by cloud operators whose offerings include PaaS-based services.

Elastic Beanstalk on AWS, What exactly is this? In a nutshell, it's a standardised and unified runtime environment for a variety of technologies such as Node.js, Python, Ruby on Rails, Java, and.NET. When selecting to employ such services, all you have to do is select the appropriate number of resources for your application.

At this stage, there is often a problem known as vendor lock-in, which refers to a company's reliance on a single source. Is it, however, truly a concern when employing the PaaS model? The project is still controlled by you, and it is built on well-known and typically open-source frameworks or technologies such as Node.JS, Django,.NET, and so on. Applications written in such technologies can be executed by any vendor that provides a runtime environment as part of their services. As a result, if your current cloud provider begins to have issues or fails to match your expectations, migrating the application to another platform will not be a problem.

Software as a Service

What exactly is it, and how can it help us? Simply described, it is a programme that is totally offered remotely by a certain provider. Typically, all that is required to utilise it is a web browser or client programme.

The supplier is in charge of all business logic and data. To use the apps supplied by the SaaS model efficiently, we do not need to hire administrators, programmers, or other specialists. E-mail is a basic illustration of how this sort of solution might be used. Each organisation makes use of e-mail, while the service is delivered in a variety of ways: • You can have your own  e-mail server.  • You may get normal hosting from one of these service providers, which serves your organisation as a mail server.

Conclusion.

The cloud frees us from the constraints of hardware. Every vendor server room, every area is the same to us. It makes no difference what the hardware is below. Our infrastructure can be restored in practically any location of the world with few clicks thanks to solutions like AWS Cloud.
